WILLIAM HENRY MORGAN, OF ALLIANCE, OHIO.

FLANGING-PRESS.

Specification of Letters Patent.

Patented Dec. 24, 1918.

Original application filed May 5, 1917, Serial No. 166,735. Divided and. this application filed December 1, 1917. Serial No. 204,883.

To all whom it may concern Be it known that 1, WILLIAM H. MORGAN, a citizen of the United'States, and a resident of Allian'ce, in the county of Stark and State of'Ohio, have invented certain new and useful'Improvements in Flanging-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will'enable others skilled in the art to which'it appertains to make and use the same.

My invention relates to improvements in forging, Hanging and other presses and is a division of application Serial Number 166735, filed by me May 5, 1917.

' Heretoforepresses of this type, designed forheavy Work, havebeen operated by hydraulic mechanism which is necessarily complicated in construction and requires constant attention, frequent repairs and adjustment of parts in order to maintain them in proper working condition.

The object of my invention is to simplify and consequentlycheapen the cost of con struction and the expense of upkeep, by dispensing with the hydraulic devices and actuating the movable platen by nuts driven by an electric motor, and it consists in the parts and combination of parts and in the details of construction as will be more fully explained and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view partly in section and partly in elevation of a press embodying my invention. Fig. 2 is an end view of the same. Fig. 3 is a sectional plan view showing the worm shaft. Fig. 4 is a view partly in section and partly in elevation of a modification. Fig. 5 is an end view of the latter, and Figs. 6 and 7 are similar views of another modification.

While I have illustrated my improvement as applied to forging presses it is equally applicable to fianging, bending and other presses, hence I would have it understood that it is not confined in its application to any particular kind of press, but is equally applicable to all apparatus of the" types above referred to.

5 represents the lower platen carrying an anvil or die 6, and 10 is a movable platen mounted to move on the four columns 7 These columns are secured at their lower ends to the lower platen 5, and they are threaded at their upper ends as shown, the said threads being engaged'by the internal threads of the internally and externally threaded nuts 8, the external threads of the latter meshing with the internal threads of the fixed nut 9, This nut 9 is secured within the upper platen 10, the four nuts 9 being located adjacent the four corners ofthe platen, or equidistant apart in the event the platens are circular instead of square or rectangular. Mounted within the upper plate'nlO, are the worm wheels 11, one for each of the movable nuts 8, each wheel being connectedby spline and groove connection with its respective nut 8. The worm Wheels 11 are housed within the top platen and are held by said housing against, movement other than their normal rotary movement, hence when they are rotated the nuts 8 move vertically up or down Withinthe hubs of the Worm wheels, their movement being permitted by the spline and groove connection between the wheels and nuts,

Mounted on top of platen 10, is the electric motor 12, the armature shaft of which carries a pinion 13 meshing witha pinion 14: on the worm shaft 15. This shaft extends lengthwise the upper platen, between the four worm Wheels housed in the latter, and meshes with said wheels so that all turn in unison and in a direction to raise or lower the platen 10. The nuts 9 and'8 and the columns 7, are so threaded that when the Worm wheels 11 are rotated by the worm shaft 15, the movable nuts 8 will all move in the proper direction and at the same rate of' the worm shaft 15, the movable nuts 8 will be rotated and moved longitudinally in the fixed nuts, and on the screws, thus moving the upper die 16, carried by the upper platen 10 toward or away from the lower die, the speed of such movement being controlled by the motor controlling devices.

In the construction shown in Figs. 4 and 5 the columns 7 b are secured to the upper movable platen 10 and threaded at their lower ends to engage the internal threads on the internally and externally threaded nuts 8, the external threads of which engage internal threads on the fixed nuts 9 secured to the four corners of the lower fixed platen 5, the worm wheels 11, which in this construction are housed in the lower fixed platen, having spline and groove connection with the mov able nuts 8 so as to permit the latter to move up and down as in the construction previously described.

The worm shaft 15 which actuates the worm wheels 11, is in this instance down adjacent the floor line, and may if desired be connected with a motor removed from the press. This construction is substantially like that shown in Figs. 1 and 2 inverted and the motor removed.

In the construction shown in Figs. 6 and 7 I have dispensed with the internally and externally threaded nuts of the previously described apparatus so that the internally threaded nuts 9 which are mounted to turn in the upper platen 10, directly engage the threads on the columns 7 and are integral with or rigidly connected with the worm wheels 11 so that they are rotated by the latter.

It is evident that changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my inven tion as claimed, hence I would have it understoodthat I do not confine myself to the exact details as shown, but consider my self at liberty to make such changes as may fairly fall within the spirit and scope of the claims.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

1. In a press for forging, fianging, etc., the combination of two platens one being fixed and the other movable, and each carrying a metal working member, a plurality of threaded columns secured to one of said platens, a nut for each threaded column, the said nuts being carried by said other platen and an electric motor and gearing carried by the latter platen for rotating the nuts simultaneously whereby the movable platen will be removed toward or away from the other platen.

2. In a press for forging, flanging, etc., the combination of two platens one being fixed and the other movable, and each carrying a metal working member, a plurality of threaded columns rigidly secured to one of said platens and passing through the other platen, nuts carried by said other platen and engaging the threads on the several columns, gearing connected with the nuts and a motor for actuating said gearing whereby the nuts will be rotated simultaneously.

3. In a press for forging, flanging, etc., the combination of two platens one being fixed and the other movable, a plurality of threaded columns rigidly secured to one of said platens and passing through the other, internally threaded nuts rigidly securedto the latter platen, an internally and externally threaded nut within and engaging the threads of each fixed nut and also engaging the threads on-the columns, a gear wheel having sliding engagement with each internal and external threaded nut and means for rotating the series of gear wheels.
